Open blanking die

Abstract

The invention discloses an open blanking die. The open blanking die comprises an upper die part and a lower die part. The upper die part comprises a die handle connected with an outer press machine, and a male die connected with the die handle. The lower die part comprises a lower die holder and a female die located in a lower die holder hole. A material guiding plate is arranged on the upper portion of the lower die holder. A discharging plate is arranged on the upper portion of the material guiding plate. The material guiding plate and the discharging plate are both of a split structure and each provided with a strip-shaped hole. The material guiding plate, the discharging plate and the lower die holder are connected through screws. The screws sequentially penetrate the strip-shaped hole of the material guiding plate, the strip-shaped hole of the discharging plate and a threaded hole of the lower die holder. The open blanking die has the beneficial effects that due to the fact that the discharging plate and the material guiding plate are of the split structure and the holes through which the discharging plate and the material guiding plate are connected with the lower die holder are formed in the manner of strip-shaped holes, when the boundary dimension of a machined workpiece changes, the position of the discharging plate and the position of the material guiding plate can be adjusted through the strip-shaped holes, and the problems that the boundary dimension of a workpiece machined by a traditional blanking die is simplex and universality is poor can be solved.

Description

technical field [0001] The invention relates to a blanking die structure, in particular to an open blanking die. Background technique [0002] Stamping is a part processing method that applies pressure to the sheet through a press and a die to make the sheet plastically formed, thereby obtaining a certain size, shape and performance. In stamping processing, a special process equipment for processing materials into parts is called a stamping die. [0003] The blanking die is an indispensable process equipment in stamping production. It is a special tool to realize stamping deformation. The structure of the blanking die should be reasonable and advanced. The blanking die is a common form of blanking die. The traditional falling die The material guide plate and the discharge plate of the material mold are integral structures, so the positions of the material guide plate and the discharge plate cannot be adjusted, and only parts with a single external dimension can be processed...
